Marriage to Royal Demons

King Tielham Famzuhr decided to find six prized maidens in his kingdom. They must be untouched by males, between 22 and 26 years old, and not attached to anyone. These six maidens will be used by the Demon King so that they can give him his heir.
A letter was sent out by messenger to announce the contest of being the royal heir carrier. Many young females were brought to the King but they were turned away for one reason or another. It took a full two years of hunting when suddenly the female was found. Soon after the second, third, fourth, fifth and sixth were found.
Out of respect for his Queen, King Tielham Famzuhr visited her in her bed chambers and slept with her frequently. He visited the six female on other nights, usually two a night. Within two months, the six females showed signs of being pregnant as well as the Queen.
In the King’s opinion all was fine. One of the six should bear a healthy baby and with the Queen being pregnant, it did not matter if she had another still born. The living baby would be swapped with the still born.

The Queen knew better than that for she had her own supporters. Months passed and when the Queen was very round and plump, she had an outing with the six females. Her supporters took the females to a hidden place where all of the females bore their babies at the same time. The Queen and six healthy were whisked away to her family home. There the six were raised as Royal Septuplets.
Five years had passed and Royal Septuplet Demons were being readied to meet their father for the first time. None of them knew that they were half-siblings. None of the servants knew who the actual full blooded Royal Septuplet was. The Queen would not say and actually had forgotten by now. She did not care which one was the full blooded heir and was happy to pull of the stunt.
That was her number one goal. She hated the fact that the King impregnated other females and this was her choice of getting him back. Particularly since Fate seen to the fact that all of them look identical to each other…. ((It does not matter if you are male or female))

The young Royalty grew up to be extravagant and insensitive to the feelings of others. Gluttony had set in. Greed grew and kept growing. Lustful, boastful and broke any Law that they saw fit to break.
By the time that fifteen years had passed, the Royal Septuplets were irresponsible and disrespectful to all, including the Big Guy, Hades. In fact, because of these young Royal Septuplets, King Hades called King Tielham into the Royal Court.
Afterwards, King Tielham called the young Royal Septuplets into his new office. The reason being told that their father wanted an interview with them and perhaps give them some kind of a bonus but instead of a bonus or some kind of a gift from King Hades, King Tielham gave them an unpleasant task.
King Tielham told his Royal Offspring that it way past time to grow up and become responsible for their actions. They will earn their own mini kingdom so that they could learn how to rule and make their mini-kingdom thrive. He wanted to get them out of his hair for not only are they irritating him constantly by bickering and tormenting the servants, breaking the Laws or causing havoc in one way or another.
They were eating so much that he, the King can no longer afford their food bill. Extravagant clothes were another problem as was other material things like treasures and books. Now all of them must pay the price of their follies.

They would be sent to The Topside to live for a while. When they fulfill their tasks, they would be allowed to come back to their own mini-kingdom with all of the benefits of a successful or not Kinglet or Queenlet.
